KP2743-1-50R - Lincoln Magnum PRO 550A MIG Nozzle 1/2 Inch Bore 1/8 Recess

Lincoln Electric Magnum PRO Nozzle: KP2743-1-50R

Maximize the efficiency and longevity of your welding operations with the Lincoln Electric KP2743-1-50R Magnum PRO Nozzle. Designed for professional welders who demand reliability, this nozzle is rated for 550A, making it suitable for the most intensive MIG/MAG welding processes. The unit features a 1/2-inch bore (ID) and a 1/8-inch tip recess, a configuration that strikes an excellent balance between gas coverage and contact tip protection. The recessed design is particularly advantageous in spray transfer modes or high-current applications, as it helps shield the contact tip from the intense radiant heat of the arc and reduces the accumulation of spatter on the tip face.

The Magnum PRO series is renowned in the industry for its durability and performance. This nozzle utilizes Lincoln's advanced engineering to maintain lower operating temperatures at the front of the gun. By keeping the nozzle and surrounding components cooler, the system reduces the adherence of spatter, making it easier to clean and maintain. This translates to less downtime for nozzle cleaning and more arc-on time for your operators. The 1/2-inch opening is versatile enough for a wide range of joint configurations, providing adequate gas flow without being so large that it limits access to tighter corners or deep grooves.

Compatibility is key in a busy shop environment. The KP2743-1-50R is designed to fit seamlessly with Magnum PRO 550A semi-automatic guns. Its threaded base allows for quick and easy replacement, ensuring that your welders can swap out consumables on the fly without struggling with seized or friction-fit parts. The secure threading also guarantees that the nozzle remains centered, which is crucial for maintaining a stable arc and uniform gas shield. When used in conjunction with Lincoln's Copper Plus contact tips, this nozzle helps extend the overall life of your gun's front-end parts, reducing total cost of ownership.

Welders Supply Company recommends this nozzle for fabrication shops, shipyards, and manufacturing plants where high amperage and high duty cycles are the norm. The robust wall thickness of the nozzle resists physical damage and heat deformation, ensuring it holds its shape over time. Whether you are pushing solid wire or flux-cored wire with gas shielding, the KP2743-1-50R delivers the consistency you need to produce high-quality welds shift after shift. Invest in genuine Lincoln Electric consumables to ensure your equipment operates at peak efficiency.
